Abstract: There is provided a method at an access node (110) providing a first cell (CELL 1), the method comprising: receiving, from a user equipment (120), over the first cell (CELL 1): a panel identifier indicating an antenna panel (1, 2, 3, 4) of the user equipment (120) and an indication that the identified antenna panel (2) is detecting radio beams from the first cell (CELL 1) and from at least one cell other than the first cell (CELL 2); and determining, based on the reception, at least one configuration for at least one of the user equipment and one or more of the cells.

Abstract: Systems, methods, apparatuses, and computer program products relating to phase tracking reference signal (PT-RS) design, for example, for discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM), are provided. One method may include forming, by a network node, a phase tracking reference signal (PT-RS) sample sequence using outer-most constellation points corresponding to scheduled modulation order of data channel, and scrambling the phase tracking reference signal (PT-RS) sample sequence with a user equipment-specific sequence.
